FAQ

I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt

How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?
Maintenance Of Solar Panels
I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually quot;connectthe two together. Any help is appreciated.
Solar Panel Fan
in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
For mono-crystalline solar panels, most warranties guarantee 90% of the original efficiency when the panel has been used for 0 years, and they guarantee 80% of the original efficiency after 25 years of use. If the original efficiency is 5%, the efficiency after 0 years of use should be 3.5%, and the efficiency after 25 years of use should be 2%. Some people believe that the actual average rate of efficiency loss is slower than that. You might retain 85% of the original efficiency after 25 years, making the average efficiency drop about 0.6% per year. After 75 years, a solar panel that was originally 5% efficient might still be about 8% efficient.
The purpose of solar panels is to harness the energy from the sun and convert it into electricity, providing a renewable and sustainable source of power for various applications.
The amount of space required for installing solar panels can vary depending on factors such as the size and type of panels, as well as the energy needs of the property. However, on average, a typical residential solar panel system requires about 100-400 square feet of roof space per kilowatt of installed capacity.
Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
Si is a neutral semiconductor, and, when combined with the other metals in the solar panel, it the panel polarizes, and releases electrons form one end, and accepts them back at the other. Like a water pump. Mg is not the major ingredient because it doesn't have the easily altered semiconductor properties Si does. To put it simply, Si is easier to work with.
I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
